Title: Exhauster water separator for vacuum pump - has draw valve opening only under atmospheric pressure inside
Inventor: SCHILLING GERALD
IPC: F16T1/24
Filed: 1974-11-07
Abstract: The separator comprises a vessel through which air or gas flows, with a drain valve discharging the accumulated liquid. The valve is spring- or weight-loaded so that when there is vacuum in the vessel it shuts, but under atmospheric pressure in the vessel it opens under the weight of the column of liquid. The vessel has a vent valve, so controlled that it opens when the maximum level of fluid in the vessel is reached, so as to connect the interior of the vessel to atmosphere, shutting again when the level falls to the minimum. The vent valve can be controlled by a main float, with an auxiliary one on the underside. The buoyancy of the latter is equal to the sum of the weight of the complete float assembly and the load from the vent valve. The buoyancy of the main float is great than the load on the valve from the atmosphere.
